Why Do I Feel Nauseous After Drinking Water?
Have you ever experienced an unusual sensation of nausea after drinking water? This perplexing phenomenon can be both inconvenient and concerning. In this blog post, we will delve into the potential reasons why drinking water may trigger nausea.

What Is Nausea?

Nausea is a distressing sensation characterized by a feeling of discomfort or unease in the stomach, often accompanied by an urge to vomit. It is not a specific illness or disease but rather a symptom that can be associated with various underlying causes.
Nausea can manifest as a result of different factors such as infections, digestive issues, motion sickness, medication side effects, pregnancy, anxiety, and certain medical conditions. The sensation of nausea is commonly accompanied by symptoms like sweating, increased saliva production, weakness, and a general feeling of being unwell. While nausea itself is not a condition, it serves as an indication that something may be amiss within the body. Understanding the underlying cause of nausea is essential in order to effectively address and alleviate the discomfort associated with this sensation.
Nausea can occur due to various factors, including illnesses, diseases, travel, overeating, intense workouts, pregnancy, hot weather, anxiety, and random upset stomachs. It can be caused by bacteria, viruses, stomach issues, motion sickness, and more. When experiencing unexplained nausea, it can be challenging to determine the exact cause. However, certain triggers like spicy or salty foods, exertion during water consumption, or excessive alcohol intake can lead to nausea. It’s important to distinguish between nausea and vomiting, as nausea is an uneasy feeling in the stomach that may precede vomiting. Additional symptoms include weakness, sweating, and increased saliva production. Typically, nausea is a temporary and unpleasant sensation.

Should I Be Concerned if I Experience Nausea After Drinking Water?

Feeling sick after drinking water is a common occurrence, and if you frequently experience nausea after consuming water, it is important to explore the possible causes. While it could be a temporary sensation resulting from an empty stomach, it is essential to consider underlying factors that may contribute to this discomfort.
Additionally, if the feeling persists or occurs frequently, it is advisable to consult a healthcare professional. They can help determine if consuming unsafe water, such as water contaminated with excessive metals or microorganisms, may be the cause. Seeking medical guidance can provide reassurance, identify any underlying health concerns, and offer appropriate solutions to address the issue.

Why Do I Feel Nauseous After Drinking Water on An Empty Stomach

When you feel nauseous after drinking water on an empty stomach, it may be a result of your body’s craving for food. Water alone does not provide the nourishment and sustenance your body needs for energy. Experiencing nausea in this scenario is a clear signal that it’s time to eat something.

Why Do I Feel Nauseous After Drinking Water on A Full Stomach

If your stomach is already full from eating, consuming a glass of water can further stretch it and potentially lead to nausea. It is advisable to avoid drinking excessive amounts of water immediately after a large meal or to wait at least thirty minutes before doing so.
It is crucial to be aware of your body’s signals in this situation. If your stomach tends to empty slowly, it may be beneficial to opt for smaller meals and consume water in small quantities throughout the day, rather than consuming large amounts of food or water in a single instance.

Why Does Cold Water or Hot Water Make Me Nauseous?

Experiencing nausea after consuming either cold or hot water can be attributed to several factors related to the temperature difference and its impact on the digestive system.

Cold Water and Nausea

Drinking excessive amounts of cold water can lead to symptoms such as nausea, vomiting, and even stomach upset. This reaction is primarily due to the significant temperature contrast between the cold water and the digestive tract. The sudden temperature difference can irritate the gastric mucosa, causing discomfort and triggering a response from the stomach.
The stimulation of the cold water on the normal gastric mucosa can lead to increased peristalsis (contractions) of the stomach, which may result in a feeling of nausea. When the body experiences these effects, it becomes more susceptible to the unpleasant symptoms associated with cold water consumption.

Hot Water and Nausea

Similar to cold water, consuming excessive amounts of hot water can also induce feelings of nausea and vomiting. The extreme temperature disparity between the hot water and the digestive system can irritate the gastric mucosa, resulting in discomfort and an unsettled stomach.
The heat from the hot water can stimulate the gastric mucosa, leading to increased stomach contractions and peristalsis. These heightened activities within the stomach can contribute to the sensation of nausea after consuming hot water.
It is important to note that individual tolerance to temperature variations can vary. Some individuals may be more sensitive to extreme temperatures, while others may not experience any discomfort. Additionally, factors such as personal preference, underlying medical conditions, and overall digestive health can influence how the body reacts to cold or hot water consumption.
To avoid or mitigate the likelihood of experiencing nausea after drinking water, it is advisable to consume water at a moderate temperature that is comfortable for you. Sipping water slowly and in moderation can also help reduce the chances of irritating the digestive system.

Will Dehydration Cause Nausea?

Insufficient water intake can lead to various unpleasant symptoms, including nausea. When the body lacks proper hydration, it may manifest as headaches, fatigue, weakness, dizziness, dry lips, and a parched mouth. Monitoring the color and odor of urine can serve as a simple indicator of dehydration. Dark yellow urine with a strong smell suggests the need for increased water consumption. It is crucial to provide the body with an adequate amount of water to sustain its vital functions.

Water Contaminants and Nausea

Nausea can be caused by various contaminants present in drinking water. Alongside the contaminants mentioned earlier, here are some additional substances that can potentially contribute to nausea:

Chemical Pollutants

Industrial chemicals, solvents, pesticides, herbicides, and fertilizers can find their way into drinking water sources, leading to nausea and other health issues if consumed at high levels.

Chlorine and Chlorination Byproducts

Chlorine, commonly used as a disinfectant in water treatment, can produce chlorination byproducts like trihalomethanes (THMs) and haloacetic acids (HAAs). Elevated levels of these byproducts in water can result in gastrointestinal discomfort, including nausea.

Microorganisms and Parasites

Untreated or poorly treated water sources, such as rivers, lakes, and groundwater, can harbor waterborne microorganisms and parasites like Cryptosporidium and Giardia. These contaminants can cause gastrointestinal illnesses, accompanied by symptoms like nausea, vomiting, diarrhea, and stomach cramps.

Volatile Organic Compounds (VOCs)

Volatile organic compounds, such as benzene and toluene, can enter water sources through industrial discharges, runoff, and improper disposal practices. When present in drinking water, high levels of VOCs can contribute to nausea and other health problems.

Pharmaceuticals and Personal Care Products

Residues of pharmaceutical drugs and personal care products, including antibiotics, hormones, and fragrance compounds, can enter water sources through improper disposal, excretion, or wastewater treatment processes. Ingesting water contaminated with these substances can potentially lead to nausea and other adverse effects.
Regular water testing and appropriate treatment methods are essential to ensure the safety and quality of drinking water. This helps reduce the risk of exposure to contaminants and subsequent symptoms like nausea.

Other Factors That May Cause Vomiting After Drinking Water

Vomiting after drinking water can also be caused by factors like pregnancy (often associated with morning sickness), electrolyte imbalance, and underlying medical conditions such as digestive disorders or gastroesophageal reflux disease (GERD). These factors can contribute to discomfort and should be considered when experiencing nausea or vomiting after consuming water. If the symptoms persist or worsen, it is advisable to consult a healthcare professional for further evaluation and appropriate treatment.

How to Relieve Nausea After Drinking Water

Experiencing nausea after drinking water can be a concerning issue. Here are some effective strategies to alleviate the problem and find relief:

Take Small Sips

Instead of drinking large quantities of water at once, try taking small sips slowly. This can help prevent overwhelming your stomach and alleviate nausea.


Ginger has long been known for its ability to soothe an upset stomach. You can try drinking ginger tea, chewing on a small piece of fresh ginger, or taking ginger supplements to help relieve nausea.


Peppermint has calming effects on the stomach and can be helpful in relieving nausea. Sip on peppermint tea or suck on peppermint candies to alleviate the discomfort.

Try Purified or Distilled Water

If you suspect the quality of your water is causing nausea, try switching to purified or distilled water. You can purchase bottled water that has undergone these treatments, or consider installing a water filtration system or distiller at home for a long-term solution.

Stay Hydrated with Electrolytes

Nausea can sometimes be a result of dehydration. Consider drinking an electrolyte-rich beverage like sports drinks or oral rehydration solutions to replenish lost fluids and electrolytes.

Avoid Solid Foods

If you’re experiencing nausea, it’s best to avoid solid foods until your stomach settles. Stick to clear fluids like water, broth, or herbal tea until you start feeling better.

Relaxation Techniques

Stress and anxiety can contribute to nausea. Engage in relaxation techniques such as deep breathing, meditation, or gentle stretching to help calm your body and mind.

Applying pressure to specific points on your body can help alleviate nausea. Try pressing on the inner wrist about three finger-widths below the base of your palm, or using special acupressure wristbands designed for nausea relief.

Avoid Triggers

Identify any potential triggers that may worsen your nausea, such as strong smells or certain foods, and try to avoid them until you feel better.


Sometimes, getting plenty of rest and allowing your body to recover can help alleviate nausea. Lie down in a comfortable position and take it easy until your symptoms improve.
If your nausea persists or worsens, it’s important to consult a healthcare professional for further evaluation and guidance. Remember, it is essential to listen to your body and address any persistent or concerning symptoms. Prioritizing hydration is crucial, but finding the right approach to drinking water that suits your individual needs can help ensure a comfortable and nausea-free experience.
